WILLIAM SYDNEY GRAHAM, OF CHICAGO, ILLINOIS, ASSIGNOR TO FEDERAL-HUBERCOMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.

LAVATORY.

Application filed June 7, 1909.

To all whom it may concern:

Be it known that I, IVILLIAM S. GRAHAM, a citizen of the United States,and resident of Chicago, in the county of Cook and State of Illinois,have invented certain new and useful Improvements in Lavatories, ofwhich the following is a description, reference being had to theaccompanying drawing, which forms a part of my specification.

My invention relates to lavatories and has for its objectthe provisionof a simple and efficient construction wherein the inlet or service-pipeconnecting member and the outlet or waste connection is intended to bedisposed beneath the basin top which may be seated or arranged beneath aslab or other frame work, and which is especially adapted for use inrailway cars and the like and known as dental lavatories.

In the drawing :Figure l is a vertical sectional view taken through theinlet or service-pipe connecting portion. Fig. 2 is a horizontalsectional view taken on the line 22 of Fig. 1. Fig. 3 is a view similarto Fig. 1, illustrating a modified form. Fig. 4 is a horizontalsectional view taken on the line el4: of Fig. 3.

The bowl or main portion of the lavatory A is hell shaped with flaringsides and a short vertical flange at the periphery. It is made of anysuitable material, such as spun metal, and is provided with the outletor waste-pipe connecting portion a, which is shown provided with aperforated cap b, any suitable style of valve or stop plug beingemployed either within this member or at the point of its connectionwith the wastepipe; but as this forms no part of my present invention,further description thereof will not be necessary. The upper edge of thebasin or body-portion A is provided with a rim 0 which may either be aseparate piece and secured to the bowl portion in any suitable manner orbe made integral therewith. This rim 0 comprises a flange curled uponitself, the curled edge being brought to within a short distance of thebody of the bowl, leaving a narrow space or slit between the curled rimand basin or body portion, as clearly shown in the drawing, therebyforming a chamber extending about the basin-top with which theservice-pipe connecting portion (1 communicates by means of port (2;

the volume and force of the water entering through port 6, being such asto force water throughout the greater portion of the chamber about theupper edge of the basin; the water passing through the narrow space orslit in the lower part of the chamber about the basin-top, thuscompelling the water to flow down the sides of the bowl or basin. Theservice-pipe connecting portion (Z is preferably made integral with therim as shown. The rim 0 is also provided with an opening f (see Fig. 1)which is placed opposite the direct passage-way or port 9, ofservice-pipe connecting portion (Z. This port or opening f is so formedas to throw a jet of water away from the wall of the basin and towardthe center of the bowl as is evident from the construction, so that notonly will the water pass from member or portion cl into the rim-chamberthrough port 6 and into the basin, but also through port or passageway gand out of portf into the basin. With this construction a jet of wateris made to play into the basin, permitting the filling of a glass withwater drawn from the same source of supply; passages e and 9 beingformed by walls a, 9.

Where it is desired to incase the lavatory as is generally done inrailway-cars and the like, the rim 0 may be provided with the outwardlyextending annular flange as at c which takes onto the slab or top memberh of the cabinet or frame surrounding the lavatory, as shown in Fig. l;or instead of the particular construction illustrated in Fig. 1, aconstruction similar to that shown in Fig. 3 may be used wherein flange0 is given more of a curl as shown, thereby giving a finished appearancewithout the casing or cabinet.

In Fig. 3 I have illustrated a modified form, wherein, instead of havingpassage or port 9 extend horizontally and into the chamber formed by rim0, the passage 9 is shown extending vertically. The passage or port 9 isto be so formed and extended as to direct a jet of water into the basinor body-portion. I have illustrated the simplest manner of accomplishingthis result, whichconsists in employing a separate tube or spout j whichmay either be screwed into the passage or port 9 as shown or otherwisesecured therein, and practically forms an extension of port or passage9. This spout or pipe j is ofcours e so formed as to throw the jet ofWater that passes therethrough, down into the basin as is evident fromthe construction. When this construction is employed it is not necessaryto have port f in the rim 0. I have shown and described What 'I believeto be the simplest and best construction, but it is evident that thesame may be altered without departing from the spirit of my invention.

Having thus described my invention, .what I claim and Wish to secure byLetters Patent is 1. A lavatory comprising a bowl portion, a detachablerim adapted to direct the Water uniformly down the sides of the bowlfrom adjacent the upper edge thereof, an inlet pipe formed integral Withthe rim, having two channels, one leading tangentially to the-rim andthe other channel lead- Gopies of this patent may be obtained for inglradia'lly through therim-into the bowl 7 end thereof, a detachable rimhaving a central portion adapted to rest Within said flange, inner andouter flanges formed integral With the said central portion andextending in substantially a horizontal direction, an inlet leading tothe bowl, having a tangentially arranged channelleading to the rimwhereby the Water Will be directed down the sides of'tlie boivl i-frornits upper edge and a radially extending channel leading from the inletWithinthe rimto the interior of the bovvlfor the purpose specified.
